So I traded the baby Jeep for a 1995 YJ 2.5L AW5. Top and interior are pretty darn good. It has a good amount of rust on it, originally from PA, about the same as the baby Jeep had being from Maine. I have named the YJ Rocky, after Rocky and Bullwinkle, because it is powered by angry squirrels. Previous owner was chasing an intermittent immediate shut-off while driving. He did:
New:
-fuel pump
-starter
-MAP sensor
-Fuel filter
-muffiler
-ignition coil
-sparkplugs and wires
-full size spare.
-Idle Air Control Valve (IAC)
-Throttle Position Sensor (TPS)
-Crank Position Sensor (CPS)
-Fuel Pump
-Distributor
-Rotor button
Wow! Also kept all the old parts so I have a good stock of spares. My research points to a bad ground, possibly fuel pump, possibly ignition, possible PCM. It got pulled onto the trailer. When I got home I started tracing wires and checking grounds hoping to find something. It would crank and crank and crank but no start. I found a plug missing a relay just hanging next to the battery, so I jammed the horn relay in there. It was apparently coincidence, but bam it started! I achieved my first goal, which was to back Rocky off the trailer and into the driveway under its own power. Drove up and down the street, cut it off, started it back up again, all was good easy fix, done right?
Went to dinner at Smithfields, got home, cranked it up for Sid and it idles for a couple seconds then dies. Back to square one, crank crank crank no spark. Check the relay I plugged in, looks fine. Scratch head and look around a lot, try to crank it more. Put a spark plug tester on it, Sid say no spark. put multimeter on coil while unplugged from distributor cap, it reads good (I think I need to double check my method there). I started doubting the spark plug test so we threw a spare plug on a plug wire, grounded it, Sid turns over the key expecting to prove to me that the plug tester was working just fine and holy crap there is spark and it starts. Couldn't repeat the issue for the rest of the night, including when I actually wanted it to start so I could go home... it starts.
-It's not fuel. It doesn't die like fuel, wont start on starter fluid.
-Seems to be completely random like a loose connection, but maybe more apt on a cold start, I will see in the morning.
-I've typed so much I forgot what I was going to say here.
Really I'm waiting for it to not start again so I can test the ignition switch and/or ignition lock cylinder. The guy's veteran Chrysler mechanic had a hunch for a bad ground in the column, and this is the general direction Sid and I are heading right now with the ignition switch. I was going to post a few pictures, but I got way into diagnosing and next thing I knew it was dark and I was tired. I am looking forward to some top down daily driving.
